Manufacturer of one of the world's fastest and easiest field tests for methamphetamine: the "Meth-1 TCL" test. First developed and marketed by NARTEC in 1990. The NARTEC kits were developed for law enforcement and other security agencies that needed quick and inexpensive field tests. They are standard presumptive tests for detection and identification of drugs, giving the officer a "probable cause" for further investigation. Confirming analyses must be conducted by a qualified person if used as evidence in court.
